Equality is fundamental notion of logic and mathematics as a whole. If computer-supported formalization of knowledge is taken into account, sooner or later one should precisely declare the intended meaning/interpretation of the primitive predicate symbol of equality. In the paper we draw some issues how computerized proof-assistants can deal with this notion, and at the same time, we propose solutions,...
The formalization of fuzzy sets in terms of corresponding membership functions is already available in machine-verified mathematical knowledge base. We show how it can be extended to provide the development of fuzzy numbers fully benefitting from the existing framework. The flexibility which is offered by automated proof-assistants allowed us to overcome some initial difficulties. Although fuzziness...
